You are on the right path for the second task. You needed use an equal sign = instead of a colon :. Also, the else statement is not needed if it is only going to pass.

def covers_all(seta):
    course_list2 = []  # use = instead of :
    for key, value in COURSES.items():
        if seta.issubset(value):
            course_list2.append(key)
        # else:  
        #     pass
    return course_list2

Post back if you need more help. Good luck!!
